Figure 4. Gene expression of antioxidant enzymes. Relative mRNA expression of (A) GSH-Px 1/2, (B) GSH-Red, and (C) SOD-1, in the eyes of normotensive (CONTROL) and hypertensive (Nω-nitro-L-arginine methyl ester, L-NAME) rats. The quantitative fold changes in gene expression were determined relative to GAPDH in each corresponding group and calculated using the 2-ΔΔCt formula. Values are expressed as mean ± standard error of the mean (SEM) of seven animals per group: ***p<0.001 versus the CONTROL group.
